467346 - Deki history view should have a link per-revision to view changes in that revision vs. previous revision

Status: RESOLVED FIXED

The Deki history view currently has a link per-revision to let you view that specific revision, but if you want to see a diff of what that revision changed, you need to select the right radio buttons and click "compare". MediaWiki has a "last" link per-revision that will bring up a diff of the selected revision against the previous revision. I find this extremely useful to quickly see what was changed in a revision.

Replaced Deki with Kuma, our new MDN platform. We have something similar in Kuma, too.

So uh, Kuma definitely doesn't do what I asked for here. If I load a revision history, say:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Windows_Prerequisites$history

There's the usual "compare revisions" radio buttons, as well as a link to view a specific revison, but there's no "diff against parent" link per-revision, which is what I really want. If you look at the Wikipedia link in comment 0, you can see that each revision has a "prev" link that just gives you the diff of the changes in that revision vs. the previous revision. *That's* what I want.

Do you mean just the 'prev' link on each item?

Yes, precisely.

Comment 5

[Luke Crouch [:groovecoder]]

:habber and/or :davidwalsh - what do you think about adding a "prev" link to each item on the history page? It would be a quick-link to compare a revision its previous revision.

Comment 6

[David Walsh :davidwalsh]

If that's what is being requested, that should be feasible if the Document object has a way to get the next and prev revisions.

Comment 7

[Luke Crouch [:groovecoder]]

Yup - doc.current_revision.get_previous() should work. 

:davidwalsh - could this be a good starter bug for :system64?
